What is the minimum duration the water spray process system must run before use for the removal of ACM?

The minimum duration that the water spray process system must run before being used for the removal of Asbestos Containing Material (ACM) is 10 minutes. This specific duration ensures that the water effectively saturates the material to be removed, thereby limiting the release of asbestos fibers into the air during the removal process. Properly wetting ACM is crucial for controlling airborne asbestos exposure, minimizing the risk of inhalation for workers and bystanders.

Running the water system for 10 minutes allows for adequate penetration and reduces the potential for the fibers to become airborne when the material is disturbed. This practice is a part of standard safety protocols during asbestos abatement to protect both the workers and the surrounding environment.
